RAILWAY-TIE FASTENER;

Specification of Letters Patent.

Application filed September 10, 1912.

. atented Sept. 2, 1913.

Serial No. 719,517.

'[b all whom, it may concern Be it known that I, ISAAC B. lVALmen, acitizen of the United. States, residing at Indcpcndence, in the countyof .lVIontgomcry and State of Kansas, have invented certain new anduseful Improvements in Railway- Tie Fasteners; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to,make and use the same, relierence being bad to the accompanyingdrawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to a railway tie, and more particularly to acombination metal and concrete tie, theprineipal object of the inventionbeing to provide a device oi. this character comprising a two-piece basemember of concrete, or the like, a metal tie bar adapted for support onthe base members, and means for connecting the metal tie with the basemembers, and with the rails, and thereby provide a substantial supportand firm connection for the rails while eliminat ing the rigidityincident to the use of a continuous concrete tie.

It is also an object of the invention to provide connection for themetal and concrete tie parts which, While holding the parts permanentlytogether, will allow one to cushion on the other and thereby stillfurther obviate the rigidity above mentioned.

In accomplishing these objects, I have provided the improved details ofstructure hereinafter described and illustrated. in the accompanyingdrawings, wherein Figure I is a plan view of a railway tie constructedaccording to my invention, illustrating its application to a pair ofrails. Fig. II is a central longitudinal section of same, showing theconnections between the parts. Fig. III is a detail perspective of ametal tie and its anchoring studs.

.teterring more in detail to the parts '1. designates the concrete tiebase which is formed in two sections, the inner ends of which are spacedto form independent members, although extending in transverse alinementrelative to the track, and, except for the central spacing, being 011?substantially the same form and size of an ordinary railway tie. Each ofthe sections has a socket 2 in its upper face for receiving the shoeoil. a metal tie member and extending vertically through the sectionfrom the base of the socket is a dowmvardly converging tapered aperture3, having vertical. grooves 3. A metal tie 4; is adapted to seat on theconcrete base members 11. and has dmvnwardly oll'set heads 5 adapted toseat in the base sockets 2 and fit snugly therein, this metal memberhaving its ends turned i'lpwardly and backwardly to :form the keeperflanges (i and pockets 7 for receiving the outer base flanges 01 therails. Depmiding from the head 5, at each end of the metal tie, is ahollow stud 8 which is tapered to fit within the base apertures 23, andhas wings 8 for seating within the socket grooves 3. At the lower end ofeach of the studs 8 is a lip 9 having an aperture 10 therein adapted forreceiving a spring key 11, the stud being of such length that its lowerend will terminate flush with the lower 'lace of the concrete base, andthe lip 5) project there below, so that the key 11 may be set in the lipaperture and bear against the bottom of the base, it being apparent thatby locking the parts together with the spring key the latter may yieldslightly to allow the parts to cushion relative to each other. The inneredge of each of the metal tie heads 5 is inclined to receive the bevelededge of a chair plate 12 which is adapted to lie over the inner flangeof the rail base and bears snugly against the inclined edge of the head.Each of the chair plates is apertured to receive a lag bolt 1.3 whichprojects through the aperture and is threaded into the hollow stud S inorder to lock the chair plate to the rail base and hold the latterfirmly to the tie. The parts describci'l are in duplicate at each end()if the tie and consequently the detailed description ol such partswhich has just been given relates equally to the parts at each end ofthe tie.

In using the device, the concrete tie sections, or bases, are arrangedin longitudinal alinement in the road bed and the metal tics sealedthereon, with the anchoring studs projected through the base apertures,and the studs locked to the bases by the spring key to form an integraltie struclnre. 'lhe rails are then seated on the tie heads with theouter base llanges located within. the pockets 7, the chair platesapplied to the rail base and tie head, and the lag bolls applied andtightened against the chair plates to firmly lock the plates to the railbase and tie head and rigidly anchor the rail to the tie.

It is apparent that with this construction an integral tie is aflordedwhich will not have the rigidity of a. continuous concrete tie, butwhich will hold the rails firmly to the tie, and in proper spacedrelation. It is also apparent that the anchoring stud and lag boltstructure will take the place of the ordinary spikes and will not becomeloosened from the tie, as the bolt has a positive locking engagementwith the stud and the latter is permanently anchored to a substantiallyindestructible base.

lVith the down set tie head a shoulder is formed against which the chairplatemay abut, so that the plate may be held rigidly in place with but asingle bolt, as the shoulder and .web of the rail will hold the plateagainst pivotal movement on the single bolt. Should it be necessary toremove a rail, the chair plate may be easily and quickly separated fromthe tie and replaced in the same position, as the threaded connectionwith the stud does not destroy the holding relation as would the removalof a spike from a wooden tie.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent, is

1. The combination with an apertured base, of a tie member, having studsprojecting through the base, means for yieldingly anchoring said studsto the base, and means for holding rails on the tie.

2. The combination with a rigid base, having sockets in its upper face,a tie having down-set heads seated in said sockets, means for anchoringthe tie to the base, chair plates, and means for attaching the chairplates to the tie. V

3. The combination with a rigid base having Vertical apertures, of a tieseated on said base and having a downwardly projecting hollow stud, saidstud having an apertured lip at its lower end, a spring key projectedthrough the aperture in said lip and adapted to bear against the bottomof the base, a chair plate, and a lag bolt projected through the chairplate and threaded into said stud, substantially as set forth.

4. The combination with a rigid base, having a grooved aperture therein,of a tie seated on the base and having a winged stud located within thebase aperture and grooves, a key for holding the stud to the base, achair plate, and means for holding the chair plate to the tie.

In testimony whereof I a'HiX my signature in presence of two witnesses.
